that guy in the other post was referring to your terminal bud. this is the main branch that forms a larger bud than the others, some trim off surrounding branches to get a single fat terminal bud, but what your doing is great, with that many branches forming an even canopy you will have many fine bud sites. just train the branches away from each other to make sure light reaches the whole plant. if your gonna trim anything you can trim off some of the low fan leaves on the soil. this lets air flow around the base of the plant and helps prevent pest and disease. another trimming option could be to prune off any small branches underneath your canopy, the ones that dont get any light, in the end small branches shaded from the light produce small sparse buds and the plant could use that energy forming buds on your canopy.
